AioGetAoResolution

Function

Retrieves the resolution of the analog output. This function supports multi-process.

Format

Ret = AioGetAoResolution ( Id , AoResolution )

Parameters

Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the Device ID retrieved from AioInit function.

AoResolution [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the variable that stores the resolution.

12	12 bit resolution
16	16 bit resolution
0	Without analog output function

Return value

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
13040	Pointer to AoResolution is NULL Specify the address of variable to parameter.
20001	This function can't be used by this device

Remarks

If the device is in operation, the function cannot be performed.

Example

Retrieves the resolution of the analog output.

C, C++	long Ret; short AoResolution; Ret = AioGetAoResolution ( Id , &AoResolution );
Python	Ret = ctypes.c_long() AoResolution = ctypes.c_short() Ret.value = caio.AioGetAoResolution ( Id , ctypes.byref(AoResolution) )
